Appeal No. 96-2056
Application No. 08/210,139
to disclose the same process parameters as recited in the
claims on appeal, i.e., the alloy powder is loaded into a
metal mold and put under pressure for 20 minutes at 550EK.
The specific alloy composition of Example 3 in the reference
is Al Ni La , which is within the scope of General Formula (I)
35 15 50
as recited in each of claims 11-14. From Figures 3-5 in
Masumoto ‘935, the values for the specific alloy composition
of Example 3 can be determined as T =approximately 515EK.,
g
T =approximately 575EK., and (T -T )= 60EK (see also column 5,x x g
lines 25-28). Accordingly, the temperature of 550EK. and time
of 20 minutes disclosed in Example 3 of the reference meets
the process limitations of claims 11 and 13 (a temperature
greater than T but less than T for a time up to (T -T ) ing x x g
minutes) and claims 12 and 14 (a temperature greater than Tg
and less than (T +T )x b for a time up to (T -T )x a inx g x g
minutes). The disclosure of Masumoto ‘935 in Example 3 of
loading the alloy powder into a metal mold under pressure
meets the claimed limitations of “producing a pressure
difference between opposite sides of the material, whereby the
material is brought into close contact against a forming mold
disposed on one side of the material” (claims 11 and 12) and
